To all whom it may concern:

Be it known that I, DAVID J. WILLIAMS, a' citizen of the United States,residing at Herrin, in the county of Williamson and State of Illinois,have invented new and useful Improvements in Window-Shades and OperatingDevices Therefor, of which the following is a specification.

This invention is an improved window shade and operating devicestherefor by means of which the shade may be raised and lowered eitherfrom the top or the bottom of a window at will, the object of theinvention being to provide improved devices of this character which arecheap and simple, may be readily installed and by means of which ashade'may be readily operated.

The invention consists in the construction, combination and arrangementof devices hereinafter described and claimed.

In the accompanying drawings: Figurel is an elevation of a shadeprovided with operating devices constructed in accordance with myinvention and showing the shade in lowered position. Fig. 2 is a sideelevation of the same. Fig. 3 is a front elevation of the same showingthe shade in raised po sition. Fig. 4 is a vertical transverse sectionalview of the same.

In accordance with my invention I provide an upper shade roller 1 whichis mounted in brackets 2 and is provided -in practice with the usualspring 3 and pawl and ratchet mechanism 4: for revolving the roller inone direction. Within the scope of my invention any suitable means maybe employed for thus revolving the roller and thus permitting it toremain stationary at any desired adjustment. I also provide a lowerroller 5 to which the lower end of the shade 6 is attached so that theshade may be wound up on the lower roller from the lower end of theshade. Cords 7 are attached to the lower roller and partly wound thereonin an opposite direction to the shade and are also attached to the upperroller. An operating cord 8 is attached to the upper roller and ispartly wound thereon in such direction as to cause it when pulleddownwardly to turn or revolve the upper roller against the tension ofthe spring. Cords 9 have their lower ends attached to the upper cornersof the roller and these cords are also made in the form,

attached to the upper roller and wound thereon in the same direction asthe operating cord 8. The cords 9 are hoisting cords.

The operation of my invention is as follows: When the upper roller isturned against the tension of the spring by drawing downwardly on theoperating cord 8 the cords 9 are unwound from the upper roller and lowerthe shade and at the same time the cords? are wound up on the upperroller and unwound from the lower roller and thereby cause the shade tobe lowered from the upper roller and to be wound up on the lower rollerand hence the shade uncovers the window, from the top. By permitting theupper roller to be revolved by its spring, which may be done by firstslightly drawing the cord 8 the cords 9 and the said cord 8 are woundupon the upper roller and said cords 9 raise the shade, causing the sameto be wound up on the upper roller and the cords 7 unwind from the upperroller and wind up on the lower roller thus causing the shade to beraised from the bottom to the upper portion of the window. The shade maybe disposed at any desired portion of the window, either at the top orbottom, or at an intermediate point as may be desired.

Nhile I have herein shown and described a preferred form of my inventionI would have it understood that changes may be proportion andconstruction of the several parts without departing from the spirit ofthe invention and within the scope of the appended claims.

Having thus described my invention, I claim 1. In combination with anupper shade roller mounted for rotation and means to turn the same inone direction, an operating cord wound on the said roller in therequired direction to cause said roller to revolve against the tensionof said roller actuating means, when said cord is drawn downwardly; ashade, a lower roller to which the lower end of the shade is attached,hoisting cords connected to the upper roller and also connected to theupper end of the shade and cords attached to the upper and lower rollersfor winding thereon.

2. In combination with an upper shade roller mounted for rotation andhaving a spring to revolve the same in one direction,

an operating cord wound on the said roller in the required direction tocause said roller to revolve against'the tension of its spring when saidcord is drawn downwardly; a

winding thereon.

In testimony whereof I affix my signature in presence of two WltIlBSSQS;

shade, a lower roller to which the lower end DAVID J. WILLIAMS. of theshade is attached, hoisting-cords con- =Witnesse's': i nected to theupper roller and also connect- A. J. WILL,

ed to the upper end of the shade and cords Copies of this patent-may beobtained for five cents each, by addressing Washington, D. 0.
